The effect of Mg treatment on the properties of Al–8.3Fe–0.8V–0.9Si alloy

This paper deals with the effect of thermomechanical processing on the mechanical properties of unmodified and modified Al–8.3Fe–0.8V–0.9Si alloys. Appreciable improvement in mechanical properties occurs on modification by Mg treatment. In general, the mechanical properties of both unmodified and modified alloys improved after hot extrusion or hot rolling. An extruded unmodified alloy was found to retain its hardness upto 200°C, and it undergoes mild ageing at 250°C after prolonged heat treatment.
